Abstract

【課題】多数の無線タグが存在する場合であっても、能率良く迅速に対象となる無線タグを探索する。 【解決手段】ハンディリーダ２００は、１つのタググループＧ１，Ｇ２，Ｇ３を構成する複数の個別無線タグＴｐ，Ｔｑ，Ｔｒ、及び、タググループＧ１～Ｇ３を代表するように対応づけられた１つの代表無線タグＴａ，Ｔｂ，Ｔｃに対し、無線通信を行うためのアンテナ１０Ｌ，１０Ｍを有し、これらアンテナ１０Ｌを介して探索対象の個別無線タグＴｐ，Ｔｑ，Ｔｒに対応する代表無線タグＴａ，Ｔｂ，Ｔｃを探索するための通信を行い代表無線タグＴａ，Ｔｂ，Ｔｃから情報を取得し、その情報取得時における通信が所定の切替条件を満たすかどうかを判定し、その判定が満たされた場合、アンテナ１０Ｍを介しそれまでとは異なる通信態様で探索対象の個別無線タグＴｐ，Ｔｑ，Ｔｒを探索するための通信を行い、個別無線タグＴｐ，Ｔｑ，Ｔｒから情報を取得する。
